Barium sulfide is a yellow or black red powder. There is a smell of hydrogen sulfide. It gradually hydrolyzes to hydrogen sulfide and barium hydroxide when it is in contact with water. Phosphorescence is emitted when trace impurities are contained. Toxic and corrosive. Used to make arsenic-free hydrogen sulfide. A sulfurizing agent is used to prepare a base of a cerium salt and a luminescent powder. Barium sulfate is made from calcination, separation and purification after mixing with coal powder. Industrial products are light brown or black powder, and also have a block shape. The relative density is 4.25 (15 ° C) and the melting point is 1200 ° C. It is insoluble in ethanol, soluble in water and decomposed into barium hydroxide and barium hydrogen sulfide, and its aqueous solution is strongly alkaline. It is corrosive and can burn the skin and cause hair to fall off. Hydrogen sulfide is also formed by reaction with water or acid, and other products are barium hydroxide, barium hydrogen sulfide or other barium salts. Hexahydrate (BaS·6H2O), hexagonal plate crystals, can be precipitated from a saturated solution. Strontium sulfide is toxic and can cause poisoning if ingested. Hydrogen sulfide is released in the presence of acid, and hydrogen sulfide and sulfur are decomposed by heating with concentrated acid. The water liberates toxic hydrogen sulfide gas in humid air.
